CHARLES E. JOHNSON, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO CORBIN CABINET LOCK COMPANY, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CONNECTICUT v l PADLOCK.

Application filed August 23, 1907.

To all whom it may concern.'

Be it known tha-t I, CHARLES E. JOHNSON, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Padlocks, of which the fol-` lowing is a full, clear, and exact description.

My invention relates to improvements in pad-locks. While the pad-lock herein, in general construction, is similar to that shown in my pending application Ser. N o. 370,133, filed April 25, 1907, the object of the present invention is to improve certain features of construction so as to provide, in place of a sliding shackle, a construction which admits of the use of a swinging or hinged shackle. While broadly the invention set forth herein is dominated by the claims of my aforesaid application, it is the purpose of the present application to cover the invention as applied to this particular species.

In the accompanying drawings-Figure 1 is a vertical section through the case, certain parts being shown in elevation Fig. 2 is a rear elevation of the hinged end of the shackle; Fig. 3 is a side elevation of the same portion; Fig. 4 is a plan view of the shackle operator,

- and Fig. 5 is a side elevation thereof.

In the drawings, 1 represents the padlock case, which is preferably made of a solid block of metal formed, for example, by the so-called extruding process, which permits a shape of any desired cross section to be formed. This solid block, is bored or -recessed at certain points and at different angles, as hereinafter described, for the purpose of permitting the various parts to be assembled.

2 represents` the shackle which is hinged at 2l to the body 1. The upper end of the case 1 is bored or recessed to receive the ends of the shackle, the recess at one side being considerably deeper than at the other side, the longer one receiving and guiding the shackle-operating device or plunger 2b. The free end of the shackle 2 is notched to receive the locking end of the locking-bolt 3. This bolt 3 reciprocates in a hole bored into one edge of the case 1 at right-angles to the firstmentioned recesses.

4 is a spring to project the bolt 3.

5 is a bolt-operating device or plug, actuated by a key 6. This plug is located in a bore in theunder side of the case, parallel with and between the two recesses in the Specification of Letters Patent.

suitable manner, so that when said plug is 2 turned it will retract the bolt against the action of spring 4. When this is done, the free end of the shackle 2 is released, whereupon the shackle may be swung by hand, or pushed open by the action of the plunger 2b, operating under the influence of spring 7. In the particular form shown, it will be o bserved that the upper end of the plunger 2b is cut away at one side, so as to clear the hinged part of the shackle as the plunger rises and the shackle swings back. There is also a small shoulder 2C formed in the shackle to engage with the upper end of the plunger, so that when the shackle is swung toward its closed position it will press back plunger 2b.

9 9 are pin tumblers located in bores parallel with the bore for the bolt 3.

10-10 are the usual tumbler springs.-

12 is a pinlocated in a suitable cross bore in the lock case 1, a portion of the pin extending slightly into a semi-annular groove -in the plug 5, so as to prevent accidental detachment of the plug, at the same time permitting sufficient rotation thereof to retract bolt 3.

16 is a cover-plate which may be suitably attached to the side of the case 1 to close the,

ends of the bores for the bolt 3 and tumblers 9. These bores may be closed in this, or any equivalent, way, as in my former construction.

The usual pin sections will, of course, be carried by the plug 5 for operating the pin tumblers upon the insertion of a suitable key.

What I claim is:

1. In a pad-lock, a one piece body or case, two recesses in the top of the same, a third recess entering the case from the bottom and between the first two, two or more bores extending into the side edge of the case and including a relatively large bore and a relatively small bore, the former intersecting the recess entering the case from the lower end, a shackle hinged in one of the upper recesses, a bolt in the aforesaid relatively lar e bore for en aging the free end of the shac le, and a bo t-operating device in the recess in the lower end of the case.

2. In a pad-lock, a solid body or case, two recesses in the top of the same, a third recess entering the case froin the bottom and bee tween the first two, two or inore bores extending into the side edge of the case and including a relatively large bore and a relatively sinall bore, the foriner intersecting the recess entering the ease frein the lower end, a shackle hinged in one of the upper recesses, a bolt in the aforesaid relatively large bore for engaging the free end of the shackle, and a bolt-operating device in the recess in the lower end of the case, and a shackle opening device including a spring arranged under the hinged end thereof.

3. In a pad-lock, a solid body or case, two recesses in the top of the saine, a third recess entering the case frein the bottoni and between the first two, two or inore bores extending into the side edge of the case and including a relatively large bore and a relatively small bore, the fornier intersecting the recess entering the case from the lower end, a shackle hinged in one of the upper recesses a bolt in the aforesaid relatively large bore for engaging the free end of the shackle, and a bolt-operating device in the recess in the lower end of the case, a shackle opening device including a spring arranged under the hinged end thereof, and a plunger 'between said spring and shackle.

4. ln a pad-lock, a solid body or case, two recesses in the top of the saine, a third recess entering the ease from the bottoni and between the first two, two or more bores ex tending into the side edge of the case and including a relatively large bore and a relayl l) end thereof, a plunger between said spring and shackle, and a shoulder on said shackle arranged to engage the end of the plunger when the shackle is open.

5. ln a pad-lock, a solid body or case, two recesses in the top of the saine, a third recess entering the case from the bottom and bef tween the ilirst two, two or more bores extending into the side edge of the ase and including a relatively large bore and a relatively sinall bore, the fornier intersecting the recess entering the case from the lower end, a shackle hinged in one of the upper' recesses, a bolt in the aforesaid relatively large bore for engaging the free end of the shackle, and a bolt-operating device in the recess in the lower end of the case, a shackle opening den vice including a spring arranged under the hinged end thereof, and a plunger between said spring and shackle, one side of the plunger being cut away or recessed to provide clearance for the hinged portion of the shackle when the latter is open.
